PTFE Piston Seals and Rod Seals - Long lasting, Low friction

PTFE piston seals (PTFE rod seals) as Spring-energized seals and memory packings are always the ideal choice for sealing static or dynamic pistons and rods.


ElringKlinger Engineered Plastics is manufacturer of PTFE seals and offers a broad range of standard PTFE piston seals and PTFE rod seals, supplemented by customer-specific special solutions.

In this area, the focus is on modified PTFE materials and compounds with specifically adapted properties.

Essential Advantages:

  • Outstanding dry-running characteristics
  • Low wear
  • Low friction
  • Variable friction conditions through choice of spring characteristics
  • Extremely low breakaway forces even after prolonged downtimes
  • No stick-slip effect even at low sliding speeds
  • High dimensional stability
  • High chemical and thermal stability
  • No volumetric change by swelling or shrinkage
  • Compact seal, suitable for O-ring assembly spaces in acc. with ARP 568 A, DIN 3771, and ISO 3601/1
  • Good cost-benefit ratio
  • Dimensions from Ø 2 to 3,000 mm available
  • Very good wiping effect with abrasive media, such as paints and lacquers
  • Sterilizable
  • Easy to rinse

Application Examples:

  • Automotive industry, e.g., in gasoline direct injection and in headlight cleaning devices
  • General mechanical engineering, e.g., in valves, solenoid valves, CNC machines, compressors, and vacuum pumps as well as tank systems
  • Aerospace industry, e.g., in landing gear systems
  • Food processing industry, e.g., in filling machines and metering systems
  • Pneumatics, e.g., in cylinders and other pneumatic components
  • Medical engineering and analytics, e.g., in chromatography and endoscopy
  • Offshore technology, e.g., as petroleum and natural gas seals
  • Chemical plant and equipment technology, e.g., in apparatus and container engineering
